High Temperature Furnace
Tungsten plate has a high heat resistance. Its high melting point allows it to serve well as the material in high-temperature furnace components. Heating elements, heat shields and boats of high-temperature furnaces are required to be resistant to a working temperature up to 1300 °C. Therefore, all of them are mainly made of tungsten plate and tungsten sheet. In the metallurgical industry, some components of electric-resistance furnaces are made of tungsten flat products. These furnaces are used to sinter refractory metals into billets and semi-finished products. The refractory metals include tungsten, molybdenum, tantalum and niobium.
Tungsten heating elements are the core part of high temperature furnaces. The working temperature can rise up to 2800°C and stay in 2300 -2350°C for a long time. The heating element is usually in the shape of a cylindrical shell or pieces of closed-end tungsten sheets riveted by tungsten bolts. Tungsten heat shields are the heat insulating part of high temperature furnaces. The riveted tungsten sheet is popular to make the most internal layer of the shields.
Tungsten Evaporation Source
Tungsten sheet is a popular material to use as an evaporation boat due to its very high melting point, low vapor pressure and stable chemical properties under high temperature. During the evaporating process, tungsten can ensure no impure particles enter the vapor and penetrate the layer adhering to the base.

Tungsten Heavy Alloy Properties And Applications
Tungsten heavy alloy plate contains tungsten content ranging from 80%-98% with small amounts of molybdenum, nickel, iron and copper elements. After going through the mixing, pressing and sintering process, Tungsten is alloyed with other metals beginning as a form of powders. 16.5-19.0 g/cm3 density of tungsten heavy alloy is the most important industrial property.
Tungsten Heavy Alloy Plate is an important material in the aerospace, military, medical industries. It is because that tungsten heavy alloy plate is characterized by low thermal expansion, high density, radiation absorption and high thermal and electrical conductivity. It is a common material chosen out of all the various hardness and wear resistance materials used for producing machining tools including lathes and dices. At the same time, it can also ensure perfect performance in high radiation exposure environment. Tungsten heavy alloy gives excellent service in applications requiring a remarkable performance in corrosion resistance, density, machinability and radiation shielding. Therefore, this makes it ideal for use in specified steelmaking, mining, aerospace and medical industries.
